1. A backlight device for a liquid crystal module, comprising:

  • a linear light source configured to emit light, the linear light source having a U-shape with a bent portion at one end of the linear light source and a pair of straight portions extending from both ends of the bent portion, respectively;

    a pair of clamps supporting the linear light source at the bent portion and one of the straight portions of the linear light source, respectively; and

    a light reflecting member arranged to reflect the light emitted from the linear light source toward a liquid crystal cell of the liquid crystal module, the light reflecting member includinga center reflecting face that is formed in a rectangular shape and disposed rearward with respect to the linear light source, the center reflecting face having a pair of openings through which the clamps are disposed, respectively,a pair of first peripheral reflecting faces that is formed in a trapezoidal shape and extends from a pair of first opposing side portions of the center reflecting face frontward and outward with respect to the center reflecting face, respectively, anda pair of second peripheral reflecting faces that is formed in a trapezoidal shape and extends from a pair of second opposing side portions of the center reflecting face frontward and outward with respect to the center reflecting face, respectively, the center reflecting face and the first and second peripheral reflecting faces being integrally formed from a sheet-like member as a one-piece, unitary member,an end portion of one of the first peripheral reflecting faces abutting an end portion of one of the second peripheral reflecting faces that is adjacent to the one of the first peripheral reflecting faces to form a corner section of the light reflecting member at a corner portion of the center reflecting face with the corner portion of the center reflecting face being located between the one of the first peripheral reflecting faces and the one of the second peripheral reflecting faces,the light reflecting member further including a coupling portion that couples the end portion of the first peripheral reflecting face with the end portion of the second peripheral reflecting face,the coupling portion including an insertion tab that extends from one of the end portion of the first peripheral reflecting face and the end portion of the second peripheral reflecting face, and a slit portion that is formed on the other of the end portion of the first peripheral reflecting face and the end portion of the second peripheral reflecting face, the insertion tab being disposed through the slit portion to couple the end portion of the first peripheral reflecting face with the end portion of the second peripheral reflecting face.
